摘要： The displacement of a pick-up head along the radial direction of an optical disk is detected, and the absolute position of the pick-up head is determined by the accumulation of the displacement, hence the apparatus knows which area on the optical disk the pick-up head currently stays. After obtaining control signals for a motor to drive the pick-up head to move along the radial direction, the apparatus calculates the displacement of the pick-up head during every stroke according the control signals. Afterward, the absolute position is determined by the accumulation of the displacement during all strokes.

摘要： A method for performing a track skip and a playback device for optical storage disks enable an accelerated track skip in the case of a non-moving storage disk in which a time is determined for the track skip of a read device between a current track and a selected track of a storage disk inserted in the playback device, as a function of the tracks to be skipped in this instance, and the read device is moved in the direction of the selected track for the determined time. In response to a track skip request, the read device is moved in the direction of a lead-in area of the optical storage disk until a starting position is detected. The time necessary for the track skip from starting position to the selected track is determined from this track.

摘要： A method and system for searching in a track in an optical storage system is disclosed. The optical storage system includes an optical pick up unit (OPU) coupled to a carriage. The method and system comprises receiving a command to indicate that the OPU is to move to a target position of the track. The method and system includes providing first and second output signals, each of the output signals having a rising edge and a falling edge. The rising and falling edges indicate movement of the carriage. The method and system further includes counting each of the rising edges and the falling edges of each of the first and second output signals and providing a sensor count for each of the rising and falling edges; a plurality of sensor counts are provided by movement of the carriage. The method and system finally includes utilizing the plurality of sensor counts to determine the distance the carriage has moved and moving the OPU to the target position based upon the plurality of sensor counts. The spindle speed at each sledge count location can be pre-calculated and stored in the look-up table, and the CLV spindle speed at target radius can be adjusted on the fly and hence reduce the seek time. By using the sledge sensor counts, the surface of the optical disk can be divided into several zones. The spindle speed can be defined and read from a look-up table for zone CAV control scheme. By dividing the disk surfaces into several zones, whenever any seek error happens during the seek operation the system processor can issue the command to re-seek to the target location rapidly without doing the recal procedure.
